Solar flares are the most explosive energy-release events in the solar corona, leading to intense particle acceleration, plasma heating and bulk plasma motions on short timescales. Core questions ...

A recent CU Boulder study suggests that confined flares are more efficient at heating plasma and producing ionizing radiation than comparable eruptive flares While many studies have compared the ...

We can now confirm that a sunspot belching out a solar flare is at least as unnerving to listen to as it is to watch. In a video recorded in March 2026, backyard astronomer DudeLovesSpace fortuitously ...

New research from the University of St Andrews has proposed that particles in solar flares are 6.5 times hotter than previously thought. The research provides an unexpected solution to a 50-year-old ...

Like the number of sunspots, the occurrence of solar flares follows the approximately 11-year solar cycle. But as the current Solar Cycle 25 approaches its peak, how are the number of solar flares ...
